This tool is a self-monitored, written record of how often and how much a patient urinates, the amount of leakage, the degree of urgency prior to voiding, and the sensation of an empty bladder after voiding. This symptom tracker may help assess patient complaints and correlate them with objective data. It may assist in differentiating those patients having high-frequency-high-volume voids from those having high-frequency/low-volume voids, consistent with OAB. The symptom tracker can also provide baseline data for follow-up comparison once treatment has been initiated.
